Logseq

Open-source outliner and knowledge base.

What it is

Logseq is an open-source outliner that stores notes as plain Markdown files on your own disk, with bidirectional links and daily notes. Files stay on disk as Markdown, so the notes outlive the app and can be versioned in Git. The trade-off is that sync and mobile polish lag behind hosted competitors, because nothing is stored on a vendor's server by default.

Logseq pricing

Logseq does not publish a plan ladder we could verify. Free.

Prices read from the vendor's own pricing page on 2026-09-08. Vendors change plans without notice — check the source before you budget.

Key features

  • Local Markdown files

    Stores every page as a plain file you own on disk.

  • Outliner with block references

    Links and embeds individual blocks, not just pages.

  • Daily notes and queries

    Captures into a dated page and pulls items back with queries.

Strengths and trade-offs

What works well

  • Your notes stay as local Markdown files
  • Open source, no vendor to depend on
  • Linked references and graph view

Where it falls short

  • Outliner structure does not suit everyone
  • Sync requires setup or a paid add-on
  • Performance drops on very large graphs

Who it is for

People who want linked notes without handing their data to a service.

Pick it or skip it

Pick Logseq if

  • Outliner-style note takers who want local Markdown or Org files they own, at no cost
  • People who want AGPL-licensed open-source software rather than a hosted notes SaaS
  • Users comfortable with alpha software who want to try the new DB version and real-time sync

Skip it if

  • You need reliable multi-device sync today: the new RTC sync and DB mobile app are in alpha by invitation
  • You are on Android and want the DB version — the README says Android is 'coming soon'
  • You want vendor support or an SLA: it is a community project

Our verdict

The strongest option if file ownership matters. Expect to solve sync yourself.
